| Sumario: | The development of efficient organic solid-state lasers requires an in-depth understanding between chemical structure, intermolecular interactions in the crystal phase, and optical and electronic properties. This study highlights these closed dependencies in novel 7-azaindole phenylhydrazone derivatives and their corresponding boron complexes, by deploying a combined approach of experimental techniques and theoretical calculations (Density Functional Theory and Time-Dependent Density Functional Theory) in the solvated and solid-state phase. Notably, it is found that when these compounds, which are weakly emissive in solution, are processed into crystalline microfibers, they experience a sharp emission enhancement and exhibit laser action at low pump fluence thresholds. This is achieved by partially inhibiting structural relaxation, which drives non-radiative decay, a critical factor for effective lasing, highlighting the potential of these materials for future optoelectronic applications. |
